BACKGROUND OF THE INVENTION

1. Field of the Invention

The specification refers to cord connectors, including, extension cord connectors.

2. Description of the Related Art

The positioning of electrical devices far from an outlet frequently requires the use of a combination of cords such as, for example, an extension cord. While extension cords greatly facilitate the range in which an electrical appliance and/or power tool can be used, use of an extension cord is not always easy. For example, in the event that an electrical appliance needs to be moved to a variety of positions during use, an extension cord can frequently unplug from either the outlet, from another extension cord, and/or from the electric appliance. This unplugging can result in the unexpected loss of power to the electrical appliance. This loss of power to the electrical appliance can be inconvenient, and can in some circumstances be dangerous.

The smallest tug or stretch on electrical cords that are connected to each other can cause those plugs to dislodge. Valuable time could be wasted if a user has to constantly stop what he or she is doing in order to fix a loose connection or retrieve a cord that has fallen into an inaccessible place. Current methods for preventing cords from disconnecting may not be readily available.

Several techniques and devices have been developed to deal with the difficulties that can arise when cords come unplugged unexpectedly. One such method of dealing with this risk is to tie cords together at the point at which they connect to each other. While tying cords together can be effective, this process can be cumbersome, takes time to complete, and decreases the reach of the cords that can be used as some of the length of the cord is lost to the knot. Another alternative to prevent cords from coming unplugged has been the integration of locking features into the plug portions of the cords. While such locking features widespread acceptance and use. Another solution to the problem of cords unplugging is the use of a feature that can be affixed to the cords to prevent them from unplugging. Similar to integrated locking devices in the plug portions of cords, such devices have proven to be costly and impractical to use, and thus have not been widely accepted by the public.

In light of these shortcomings, new devices and techniques are required to connect cords to prevent the unexpected interruption of power to an electrical appliance.

As also seen in FIG. 2, the second receiving area 118 is smaller than the dimension of the first plug 204. Thus, the second loop 116 can slide longitudinally along the first cord 206 away from the first plug 204, but cannot slide longitudinally along the first cord unit 202 past the first plug 204.

A person of skill in the art will recognize that a cord system 200 can include more of fewer components than those specifically outlined above, and that the components of the cord system 200 can be used in the same or different fashion as outlined above.

Some embodiments relate to methods of using a cord connector 100 with the first cord unit 202 and a second cord unit 208. In such an embodiments, the first plug 204 of the first cord unit 202 can be connected to and mate with the second plug 210 of the second cord unit 208. After the first and second cord units 202, 208 are engaged, the cord connector 100 can be connected to the cord system 200. In some embodiments, for example, the cord connector 100 can be connected to the cord system 200 by passing a portion of the first and/or second cord unit 202, 208 through the first access opening 112 into the first receiving area 110 of the first loop 108. After positioning the elongate member 102 of the cord connector 100 such that the elongate member 102 extends along the first plug 204 and the second plug 210, a portion of the first and/or second cord units 202, 208 can be passed through the second access opening 120 into the second receiving area 118 of the second loop 116, which passing thereby secures the cord connector 100 to the first and second cord units 202, 208. In some embodiments, for example, the method of using the cord connector 100 with the first cord unit 202 and the second cord unit 208 can further include selecting a cord connector 100 having an elongate member 102 approximately the same length as the connected first plug 204 and the second plug 210. As discussed above, as the first loop 108 and the second loop 116 can be sized and shaped to allow movement of the cord connector 100 along the longitudinal axis of the first cord unit 202 and/or the second cord unit 208 to be constrained by the position of the first plug 204 and/or the second plug 210, the function of the cord connector 100 can be advantageously improved by selecting a cord connector 100 having a length of the elongate member 102 approximating the length of the connected first plug 204 and the second plug 210. In one specific embodiment, the cord connector 100 can be selected such that the elongate member 102 is approximately 0.01 inches, 0.1 connected first plug 204 and the second plug 210.

A person of skill in the art will recognize that the above outlined steps of the method of using a cord connector 100 with a cord system 200 can be performed in a different order and that additional and/or fewer steps can be used in performing the method.

The foregoing description details certain embodiments of the systems, devices, and methods disclosed herein. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the systems, devices, and methods can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the technology with which that terminology is associated.

It will be appreciated by those skilled in the art that various modifications and changes may be made without departing from the scope of the described technology. Such modifications and changes are intended to fall within the scope of the embodiments. It will also be appreciated by those of skill in the art that parts included in one embodiment are interchangeable with other embodiments; one or more parts from a depicted embodiment can be included with other depicted embodiments in any combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged or excluded from other embodiments.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
